FURNACES USED ON LP GAS MUST BE EQUIPPED WITH 100% SAFETY SHUT-OFF CONTROLS. CONVERSION
WITH THE CORRECT KIT WILL MEET THIS SAFETY REQUIREMENT. CONVERSION WITH THE WRONG KIT CAN
LEAD TO A FIRE OR EXPLOSION RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
The conversion of Air Conditioning Division furnaces must be made by a qualified service professional using factory spec-
ified or approved parts. The following conversion kits must only be used on the furnace models and gas control systems
for which they are shown. If you do not find your exact furnace model number in the kit selection chart, contact your dis-
tributor or manufacturer for help in verifying the correct kit selection for your equipment. Do not substitute kits or kit com-
ponents in order to avoid risk of dangerous conditions that may result in personal injury or property damage.
IMPORTANT NOTE FOR INSTALLATIONS AT ELEVATIONS ABOVE 2,000 FEET (610 METERS): The main burner ori-
fices in your furnace and in Natural Gas to LP Gas (Propane) Conversion Kits are sized for the nameplate input and intend-
ed for installations at elevations up to 2,000 feet only. For elevations above 2,000 feet (610 meters), the burner orifices
must be sized to reduce the input as follows:
In the USA: Reduce the input 4% for each 1,000 feet (305 meters) above sea level.
See Chart III in this Conversion Kit Index for proper orifice sizes for the elevation at which the specific unit is
to be installed. The Conversion Kit Index is shipped with each unit and with the Natural Gas to LP Gas
(Propane) Conversion Kits.
In Canada: A high altitude conversion kit available from the manufacturer must be used for operation on natural gas at ele-
vations of 2,000 - 4,500 feet (610 - 1373 meters) above sea level. See Chart II in this Conversion Kit Index for
the Canadian High Altitude Kit model number.
The proper high altitude orifices and instructions are included with the standard Natural Gas to LP Gas
(Propane) Conversion Kits for operation on LP Gas (Propane) at elevations of 2,000 - 4,500 feet (610 - 1373
meters) above sea level in Canada. A special high altitude kit is not required in this case. Simply use the prop-
er orifice size specified in Chart III in this Conversion Kit Index for elevations of 2,000 - 4,500 feet (610 - 1373
meters) in Canada.
NOTICE: THE CONVERSION SHALL BE CARRIED OUT BY A MANUFACTURER'S AUTHORIZED REPRESENTA-
TIVE, IN ACCORDANCE WITH THE REQUIREMENTS OF THE MANUFACTURER, AND STATE, PROVIN-
CIAL, OR TERRITORIAL AUTHORITIES HAVING JURISDICTION AND IN ACCORDANCE WITH THE
REQUIREMENTS OF ALL LOCAL CODES, THE NATIONAL FUEL GAS CODE, ANSI Z223.1, CAN/CGA-
B149.1, OR CAN/CGA-B149.2 INSTALLATION CODES.
HOW TO IDENTIFY THE CONTROL SYSTEM
ON THE FURNACE TO BE CONVERTED
The model number and the first two letters of the serial number on the furnace to be converted are required to select the
proper conversion kit. This information is located on the rating plate of the furnace. The first two characters of the serial
number designate the control system as applied by the manufacturer and the type gas it was manufactured to burn.
STEP 1. Locate the first two letters of the serial number in Chart I. This is the control system on the furnace. All furnaces
are manufactured to burn natural gas.
STEP 2. Determine the altitude at which the furnace is to be installed.
